-
- when VPP-AC rises, a charging current flows from the
oscillator 40 to the load Cout through the transistor T31, to charge the load Cout and accordingly increase the potential OUT: T31 works in ohmic conduction, at least at the end of charging, - when VPP-AC is constant at VPP-DC, OUT is constant and equal to VPP-DC−VT, VT being a potential threshold of T31,
- when VPP-AC decreases, a discharge current flows from the load Cout to the
oscillator 40 through the diode. D34 of the transistor T31, to discharge the load Cout and reduce the potential OUT accordingly.
